We performed all calibration and imaging procedures using the 31DEC19 release of the Astronomical Image Processing System [1]} and ParselTongue [2]}.
PTF11qcj was clearly detected at both frequencies. At 1.66 GHz, in particular, given the relatively large separation between PTF11qcj and the complex gain calibrator J1358+4737 (\(\approx 7.6^\circ \) )
we used self-calibration to correct for the residual phase errors towards PTF11qcj and obtain a reliable flux density measurement.
The final VLBI images are presented in Figure REF .
